@phrygn:Just to avoid any misunderstanding: Modded drivers are generally not accepted by the OS Setup, if you have integrated them into the OS image or load them while starting the OS installation.Although my mod+signed drivers have been correctly digitally signed, it is not easy to get them installed within the early stage of the OS Setup. Reason: The OS Setup doesn't accept the digitally signature of a Company (here: Win-RAID CA), which it doesn't know and whose trustworthiness cannot be confirmed by importing the Certificate (impossible during the OS Setup).So it may be possible, that you have to integrate the MS NVMe Hotfix for Win7 to get Win7 installed onto your Samsung PM981, but you should be able to get my mod+signed driver installed once the OS is up and running (don't forget to import the Certificate before you start with the manual driver update).

Thanks for your insight. I was able to successfully modify install.wim and boot.wim on my W7 installer to include your drivers (using DISM) and everything has been going smoothly so far. The "DISM GUI" offered by codeplex has a feature that allows you to force unsigned drivers. Just thought I'd let you know! Thanks again.

I recently bought one ssd XPG sx9000 and intended to use with windows 7. Adata apparently only gives one copy of acronis to clone from one hdd to ssd, but I'd like to install directly on ssd since another disk isn't always available. I tried to load some drivers found here, but the ssd was never recognized. Later I found out MSI Smart Tool and was able to create an installer which was supposed to be ready for ssds.. and it recognize mine, but the installation was painfully slow, so I gave and installed windows in a regular hdd then cloned it to the ssd. I don't know if the performance is at it's best and if there are some issues starting programs due to the cloning aproach, so I wonder If I could get any help here to get a pure driver or at least someone giving ideas where to look for it.

@x58haze:Thank you very much for having done the benchmark comparison tests and for the screenshots, which verify, that there is no measurable performance difference between the MS in-box AHCI driver and the mod+signed AMD AHCI driver v1.3.1.277.Conclusion: Only the stability of the driver will decide, which driver is the better choice.Remark: Very interesting for me is the fact, that all your 3 on-board SATA AHCI Controllers are listed within the "System devices" section of the Device Manager. Usually they are listed within the "IDE ATA/ATAPI Controllers" or "Storage Controllers" section.

The choice of the "best" driver doesn't depend on the HDD or SSD model, but only on the specific on-board SATA AHCI resp. SATA RAID Controller shown within the Device Manager by its HardwareIDs (right-click onto the related SATA Controller > "Properties" > Details" > "Property" > "HardwareIDs").So please post the HardwareIDs of your in-use SATA Controller and I will try to give you my recommendation regarding the "best" AHCI or RAID driver.

Your welcome. Btw i can help you for further test if you want. Also wanted to tell you that I had to back to the Microsoft Ahci, because i was getting insane latencies on the storport.sys reported by last version of Latency Mon, over 2500us

After that I looked for drivers from MSI and AMD, but they require amd catalyst and don't detect it, so I'll try a clean install. My real challenge still is doing a direct installation (or reinstallation) of windows 7, instead of cloning it from another drive.

@HotLobster:On board of your ADATA XPG SX9000 NVMe SSD is a Marvell NVMe Controller 88SS1093, but Marvell hasn't (yet) released an NVMe driver, which natively supports this Controller.Consequence: Only the generic MS NVMe driver is able to detect and to manage this specific Marvell NVMe Controller.Since Win7 doesn't have any MS in-box NVMe driver, you will have to integrate the related MS NVMe Hotfix. For details please look >here<.

@Dime_Baggins:Within >this< thread you can find the answer to your question.At the bottom of the start post is a table with Intel AHCI driver versions, which I recommend to use with Intel 7-Series Chipset Mobile systems.Alternatively you can use the generic MS AHCI driver, which is very good as well.
